Title: Pipeline monitoring apparatus
Inventor: JIYON AARU ADAMUSU
IPC: G01C19/00
Filed: 1989-12-12
Abstract: PURPOSE: To obtain an accurate measuring value by correcting the measured value of an inertia measuring system according to the information indicating the relative positional relationship between a carrier means and pipe line. CONSTITUTION: A pig 1 traveling in a pipeline 2 to measure a condition uses electric power generated by a generator 11 through a battery pig 15 for the electric power of measuring instruments. An inertial measuring system 17 consists of a three-way gyroscope and three-way accelerometer to calculate the curvature and orientation of the pipe lien 2. Caliper sonar converters 19, 21 measure a distance between a pipe wall and the pig 1 by a supersonic range- finder. Doppler sonar converters 23, 25 utilize the Doppler effect caused by sound waves to measure the speed of the pig 1. The measured value of the inertia measuring system 17 is associated with these sonar measured values to be recorded on a digital recorder.

IPC: C08L67/00
Filed: 1992-11-09
Abstract: PURPOSE:To provide the subject composition containing a polybutylene terephthalate- based resin produced in the presence of potassium titanyl oxide as a catalyst and exhibiting a specified viscosity, a filler and a flame retardant, excellent in thermal aging resistance and hydrolysis resistance and useful for an electric and electronic component, etc. CONSTITUTION:Dimethyl terephthalate and 1,4-butane diol are charged into a reaction tank and potassium titanyl oxalate as a catalyst is added thereto. The resultant mixture is heated and a transesterification is carried out while gradually raising the temperature from 145 deg.C to 230 deg.C under atmospheric pressure. The reaction mixture is subsequently subjected to polycondensation by reducing the pressure of the reaction system from atmospheric pressure to 0.3mmHg and raising the reaction temperature from 230 deg.C to 260 deg.C. Thereby, a polybutylene terephthalate-based resin exhibiting >=0.6dl/g intrinsic viscosity is synthesized. One or both of fillers such as glass fiber and a flame retardant such as brominated polycarbonate are added thereto, thus producing the objective resin composition remarkably excellent in thermal aging resistance and hydrolysis resistance and free from remarkable deterioration of physical properties even after use under a high-temperature and high-humidity condition for a long period.

Title: Light-shielding device
Inventor: AOKI MAKOTO
IPC: G02F1/13
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To improve availability for seeing-through by a method wherein a semi-light- transmitting member in which light-transmitting parts and a plurality of light-shielding parts are uniformly distributed on a plane is oscillated at a specified amplitude along the distribution plane. SOLUTION: In a semi-light-transmitting member 12 made of fabric woven in large meshes, fibers constitute light-shielding parts 11 while apertures among the fibers constitute light-transmitting parts 10. As the semi-light-transmitting member 12 is moved in a circular motion or a reciprocating motion at a specified amplitude with oscillation given by an oscillating device 13, outside light coming in through a window W is partly shielded with the light-shielding parts 11. As the light-transmitting parts 10 and the light-shielding parts 11 are moving constantly, transmitted light decreases momentarily while the light is transmitted successively through the entire body of the semi-light-transmitting member 12. Therefore, the amount of transmitted light can be decreased without obstructing visibility. As occasion demands, a semi-light- transmitting member made of a flat liquid crystal panel is provided, and light-shielding areas are formed at optional places in the liquid crystal panel with operations applied to the liquid crystal, thereby decreasing the amount of light taken in while the state of things at the exterior can be seen through.
